I don't know what travel list you are looking at. There are currently 194 countries in the world ( I think...some little country seems to break into 2 every week), so...are there 194 countries on the list you are looking at?
I guess it has to do with who created the list that you are looking at and why. I live in Belize now but 3 to 4 years ago I had no idea the country existed. A country of about 300,000 does not register on everyone's "radar" screen.
